SASI Bypass

SASI Bypass is a weight-loss surgery that combines two approaches: first, the stomach is made smaller (like a sleeve gastrectomy), and then a connection is created between the stomach and the lower part of the small intestine. This helps you feel full with less food and reduces calorie absorption, leading to substantial weight loss.

The Single Anastomosis Sleeve Ileal (SASI) Bypass is a novel metabolic bariatric procedure that pairs a standard sleeve gastrectomy with a side-to-side gastroileal anastomosis approximately 250–300 cm from the ileocaecal valve. This creates both restrictive and malabsorptive components without the need for a Roux limb or a second anastomosis. Emerging evidence suggests SASI achieves comparable weight loss to Roux-en-Y gastric bypass with a potentially lower complication rate and shorter operative time.

For patients with severe obesity or metabolic conditions like type 2 diabetes who do not achieve adequate results with sleeve gastrectomy alone, SASI Bypass offers an additional surgical option.
